Sanlight Series Q: The benchmark horticultural LED lighting for your indoor grows
The Sanlight Series Q range represents the best in LED lighting for indoor cultivation. These Austrian panels combine exceptional luminous efficacy of 2.9 µmol/J with a perfectly calibrated full-spectrum to maximize photosynthesis and plant development. Designed without a fan, they operate in total silence while offering a lifespan exceeding 50,000 hours.
Why choose Sanlight Series Q lighting
Sanlight technology stands out for its scientific approach to horticultural lighting. Each Series Q panel integrates Samsung LM301H diodes selected for their stability and spectral rendering. The spectrum covers 380 to 780 nm with optimized peaks at 450 nm (blue), 660 nm (red), and 730 nm (far-red) to stimulate flowering and trichome formation. This spectral precision allows for 15 to 20% higher yields compared to generic LEDs, while consuming 40% less than equivalent HPS lighting.
Passive cooling by aluminum heat sinks completely eliminates noise pollution and fan failures. The panels operate at surface temperatures below 45°C, reducing the thermal load of your grow space. This design also allows for closer installation to the foliage without risk of burns, thus optimizing light penetration.
How to choose your Sanlight Series Q panel
The choice of model primarily depends on your grow area and energy budget. For a 60x60 cm tent, a 50W Q1W is largely sufficient as a supplement or for young plants. Areas from 80x80 cm to 100x100 cm require a Q3W (120W) for homogeneous coverage. For larger spaces of 120x120 cm, opt for a Q4W (190W) or combine several Q3W depending on your setup configuration.
Suspension height varies according to the growth stage: 60-80 cm for seedlings and cuttings, 40-60 cm during vegetative growth, and 30-40 cm during flowering. This modularity allows you to adapt the light intensity without a dimmer, simply by adjusting the distance. For finer control, M-Dimmer (manual) and BT-Dimmer (Bluetooth) dimmers allow intensity to be varied from 1 to 100%.
Frequently Asked Questions
What is the difference between the Q series and the EVO series from Sanlight?
The Series Q uses Samsung LM301H diodes with an efficiency of 2.9 µmol/J, while the EVO series integrates newer diodes reaching 3.1 µmol/J. The EVO series also offers a slightly enriched far-red spectrum (730 nm) and better light uniformity thanks to a new optical design. However, the Series Q remains more affordable while offering performance largely sufficient for most growers. The yield difference between the two series is approximately 5-7% in favor of the EVO.
What size Q-Series panel should I choose based on my grow area?
For a 60x60 cm surface, the Q1W (50W) is perfectly suited for low-demand plants or as supplementary lighting. An 80x80 cm tent requires a Q3W (120W) to achieve the recommended 400-600 µmol/m²/s during flowering. For 100x100 cm, the Q4W (190W) is ideal, while 120x120 cm surfaces benefit from two Q3W for better light distribution. These recommendations are based on a 40 cm suspension during flowering with a target PPFD of 500 µmol/m²/s.
How to properly install and hang a Sanlight Q-Series panel?
Installation is done via the integrated fixing points on the aluminum frame, compatible with all standard suspension systems (yo-yo, chains, cables). Maintain a minimum distance of 15 cm between the panel and any surface to ensure air circulation around the heat sinks. In a tent, attach the suspension straps to the structural bars, never directly to the fabric. Regularly check the tension of the suspensions as the weight of the panels (2.5 to 4.5 kg depending on the model) can cause poor quality fixings to fail. Always use the supplied power cable and avoid cheap extension cords that can cause voltage drops.
Are the dimming options (M-Dimmer or BT-Dimmer) compatible with all Q-Series models?
All Q-Series panels are equipped with an RJ12 connector allowing the addition of an external dimmer. The M-Dimmer offers manual control via a rotary potentiometer, ideal for simple installations. The BT-Dimmer adds control via smartphone with the Sanlight app, allowing programming of light cycles and remote control. A single dimmer can control up to 30 panels in a chain thanks to the supplied connection cables. This feature is particularly useful for simulating natural light variations and optimizing power consumption according to your plants' needs.
What maintenance is required to maintain the light performance of my Q-Series panel over time?
Maintenance of Q-Series panels is limited to monthly dusting of the aluminum heat sinks with a dry brush or a low-power vacuum cleaner. Absolutely avoid water or solvents that could damage the electronics. Quarterly check the condition of the connections and the power cable. Light degradation is less than 10% after 50,000 hours of use, which is approximately 10 years of operation 12 hours/day. No component replacement is necessary during this period, unlike HPS bulbs which lose 20% of their flux in the first year. This exceptional longevity makes the Q-Series a particularly profitable investment in the long term.
